| W5OLF WSPR beacon - complete - no PC needed |
This WSPR-AXE really is a very impressive little rig, in my case for 10m WSPR. Because of my current disabled state - I find
all electronics building just about impossible - Jay very kindly sold me a built unit to evaluate. Results in just a few hours of operating have been truly impressive. No PC is needed as long as the push button is pressed at the start of an even minute. Jay says it stays stable for weeks thereafter. I ran mine for 3.5 hours and got masses of decodes. After lunch it has been getting LOTS of spots from the USA. I am sure it will reach Australia soon.
The unit needs about 15 minutes to frequency stabilise and is always on (the PA can be turned off), but it randomises the slots within the WSPR transmit window. This means it is unlikely to be "clobbered" by more powerful stations or cause others co-channel issues. 500mW seems plenty. In a word - BRILLIANT.
Best DX report (so far) today is
FR1GZ (9724km).

I still have a 30m W5OLF WSPR transmitter kit. I should build it one of these days. It's just a matter of how I divide my time. Too many things in this hobby I like. 73, Bas
I can see myself buying versions for other bands Bas. Possibly 20m? I am VERY impressed with my 10m unit. The likely kit price of $49(?) plus shipping sounds good value.
I think the latest versions are new. They now transmit continuously but randomise the TX frequency within the WSPR window to minimise interference.
So far, I have "sync'd" my unit to the start of an even minute at the start of the day and not touched it again all day. Jay claims it will be OK for weeks.
